Physical activity has other neurophysiological benefits including improving neuroplasticity and neurogenesis. Neuroplasticity is the brains ability to grow and develop new neural pathways . While neurogenesis is a form of neuroplasticity, it is different in the sense that it is particularly associated with the formation and growth of new neurons after birth (post-natal). Princeton University conducted a study to examine whether exercise does reduce anxiety in addition to augmenting the growth of neurons in the hippocampus (involved in thinking and emotional responses). There were two arguments to this study, firstly as the new neurons develop in abundance they are usually more excitable than their mature counterparts, and so it was hypothesized
